DETAILED DESCRIPTION

[0034] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0035] The following will be described in combination with Figures 1-6A polarized lens is described.

[0036] In one aspect, the embodiments of the present application provide a polarized lens, such as Figures 1 to 3 As shown, the polarized lens mainly comprises a lens body 100.

[0037] Specifically, the installation side of the lens body 100 is provided with a light source installation groove 150. It can be understood that the light source installation groove 150 has two opposite side walls and a bottom wall. Specifically, in the present embodiment, the two side walls are defined as a first groove wall and a second groove wall. The first groove wall of the light source installation groove 150 forms a first light entrance surface 113. The bottom wall of the light source installation groove 150 forms a second light entrance surface 123. The second groove wall of the light source installation groove 150 forms a third light entrance surface 134. It can be seen that the first light entrance surface 113, the second light entrance surface 123 and the third light entrance surface 134 of the present embodiment are located on the same side and are connected in sequence. The light source installation groove 150 is used for installing a light source. The light source provides incident light rays for the first light entrance surface 113, the second light entrance surface 123 and the third light entrance surface 134 at the same time.

[0038] In the present embodiment, one side of the lens body 100 is the installation side, and the opposite side is the light exit side of the lens body 100. The lens body 100 is installed in the shell 300 mentioned below through the installation side. The light source is located on the installation side, that is, the installation side is the light entrance side. The exit light rays exit from the light exit side.

[0039] In the present embodiment, the lens body 100 is provided with a reflection curved surface 112 for twice total reflection of the incident light rays of the first light entrance surface 113, a reflection inclined surface 122 for once total reflection of the incident light rays of the second light entrance surface 123, and a pair of oppositely arranged reflection planes for once total reflection of the incident light rays of the third light entrance surface 134. The lens body 100 is also provided with a first light exit surface 111 for light exit of the reflection curved surface 112, a second light exit surface 121 for light exit of the reflection inclined surface 122, and a third light exit surface 131 for light exit of the reflection planes.

[0040] Specifically, the emergent light rays of the first light exit surface 111, the second light exit surface 121 and the third light exit surface 131 are arranged to be deflected towards the same side as the incident light rays of the corresponding first light entrance surface 113, the second light entrance surface 123 and the third light entrance surface 134. Thus, after the incident light rays enter the first light entrance surface 113, the second light entrance surface 123 and the third light entrance surface 134, they are subjected to twice total reflection by the reflection curved surface 112 and exit from the first light exit surface 111, subjected to once total reflection by the reflection inclined surface 122 and exit from the second light exit surface 121, and subjected to once total reflection by a pair of reflection planes respectively and exit from the third light exit surface 131. The emergent light rays are not emitted along the direction of the incident light rays, but are emitted at a certain angle of deflection, thus achieving the effect of polarization. For some special installation occasions, for example, when the lower surface of the eaves cannot be installed with a lighting lamp due to the narrow space, the polarized lens of the embodiment can be used, which is convenient to install. The lighting lamp using the polarized lens of the embodiment can be installed on the wall on one side of the eaves. Since polarization can be achieved, the same downward irradiation effect can be achieved. In addition, the installation space of the wall is larger, and the installation is more convenient than that on the lower surface of the eaves. Moreover, for different specifications of lamps, there is more selection space.

[0041] According to one embodiment of the present application, the lens body 100 comprises a first sub-lens 110, a second sub-lens 120 and a third sub-lens 130 connected in sequence along a first direction, the reflection curved surface 112 is arranged on the top surface of the first sub-lens 110, and the first light entrance surface 113 and the first light exit surface 111 are both located on the bottom surface of the first sub-lens 110 and are separated by the second sub-lens 120. The reflection curved surface 112 is an outward convex curved surface, and the incident light rays of the first light entrance surface 113 are adapted to exit from the first light exit surface 111 by twice total reflection by the outward convex curved surface. The curvature of the outward convex curved surface can be different, for example, the curvature can change from large to small and then to large, or from small to large, etc., as long as the incident light rays of the first sub-lens 110 can exit from the first light exit surface 111 by twice total reflection. It can be understood that the emergent light rays are emitted once by refraction after passing through the first light exit surface 111 due to the change of medium.

[0042] According to one embodiment of the present application, the second light entrance surface 123 is arranged on the side surface of the second sub-lens 120 and is connected with the first light entrance surface 113, one end of the reflection inclined surface 122 is connected with the bottom surface of the first sub-lens 110, specifically, the one end of the reflection inclined surface 122 is connected with the first light exit surface 111, of course, the reflection inclined surface 122 needs to avoid the light exit area of the first light exit surface 111, the other end of the reflection inclined surface 122 is connected with the second light exit surface 121 at an angle, the second light exit surface 121 is located below the first light exit surface 111, and the second light exit surface 121 can be arranged parallel to the first light exit surface 111. The incident light rays of the second light entrance surface 123 are adapted to exit from the second light exit surface 121 by once total reflection by the reflection inclined surface 122, and the emergent light rays of the second light exit surface 121 are deflected towards the same side as the incident light rays of the second light entrance surface 123. Figure 3It can be seen that the outgoing light is just perpendicular to the second light exit surface 12, and the outgoing light does not refract directly out of the light.

[0043] According to an embodiment of the present application, the third light entrance surface 134 is arranged on the side surface of the third sub-lens 130 and is connected with the second light entrance surface 123, one of the pair of reflection planes is connected with the third light entrance surface 134, which is defined as the first reflection plane 132, the other of the pair of reflection planes is connected perpendicularly with the second light exit surface 121, which is defined as the second reflection plane 133, the second reflection plane 133 avoids the light exit area of the second light exit surface 121 to avoid blocking the outgoing light, and the pair of reflection planes can be arranged in parallel. The third light exit surface 131 includes two, the two third light exit surfaces 131 are arranged on the bottom surface of the third sub-lens 130 and are located between the pair of reflection planes; the two third light exit surfaces 131 are connected at an angle. The third light entrance surface 134 is adapted to emit light from the adjacent third light exit surface 131 by one-time total reflection through one of the reflection planes, and is adapted to emit light from the adjacent third light exit surface 131 by one-time total reflection through the other of the reflection planes, specifically, part of the incident light of the third light entrance surface 134 is adapted to emit light from the adjacent third light exit surface 131 by one-time total reflection through the second reflection plane 133, and the other part of the incident light of the third light entrance surface 134 is adapted to emit light from the adjacent third light exit surface 131 by one-time total reflection through the first reflection plane 132 after total reflection through the second reflection plane 133. Thus, the first sub-lens 110, the second sub-lens 120 and the third sub-lens 130 all emit light from the same side and from different light exit surfaces.

[0044] It can be understood that the outgoing light is refracted once after passing through the third light exit surface 131 due to the change of medium.

[0045] According to an embodiment of the present application, the reflection inclined surface 122 is connected at a 45-degree angle with the second light exit surface 121; the incident light is horizontally irradiated on the 45-degree reflection inclined surface 122 from the second light entrance surface 123, is deflected by 90 degrees (one-time total reflection) and emits light from the second light exit surface 121. The outgoing light of the first light exit surface 111, the second light exit surface 121 and the third light exit surface 131 is arranged at a 90-degree angle with the incident light of the corresponding first light entrance surface 113, the second light entrance surface 123 and the third light entrance surface 134. This enables the polarizing lens of the present embodiment to polarize light by 90 degrees, so that the polarizing lens can be used in special occasions, such as when the lamp is installed on the wall on one side of the eaves, to achieve the effect that the light source is offset to one side but can emit light downward. Figure 6 It can be seen from the light distribution diagram that the polarizing lens can polarize light by 90 degrees. Thus, it can be applied to special occasions, such as when the lamp is installed on the wall on one side of the eaves, to achieve the effect that the light source is offset to one side but can emit light downward.

[0046] As shown in FIG. 1, the polarizing lens includes a first sub-lens 110, a second sub-lens 120 and a third sub-lens 130, and the first sub-lens 110, the second sub-lens 120 and the third sub-lens 130 are arranged in sequence from left to right. Figure 5As shown, according to one embodiment of the present application, the first sub-lens 110, the second sub-lens 120 and the third sub-lens 130 are integrally extruded and extend along a second direction, which is perpendicular to the first direction, that is, if the first direction is the height direction of the lens body 100, the second direction is the length direction of the lens body 100, the first sub-lens 110, the second sub-lens 120 and the third sub-lens 130 are sequentially connected along the height direction, the first sub-lens 110, the second sub-lens 120 and the third sub-lens 130 are stretched to form the lens body 100 along the same direction, and the specific length of the stretching depends on the required length of the polarizing lens. Accordingly, the light source mounting groove 150 is in the shape of a strip matching the length of the lens body 100.

[0047] According to one embodiment of the present application, the number of the second sub-lens 120 is two, the two second sub-lenses 120 are stacked along the light emitting direction, and the light emitting areas of the two second light emitting surfaces 121 are staggered with each other on the projection plane of the light rays. Through the arrangement of the other second sub-lens 120, the blank area between the second sub-lens 120 and the third sub-lens 130 can be filled, so that the light emission is more uniform.

[0048] According to one embodiment of the present application, on the projection plane of the light rays, the light emitting area of the first light emitting surface 111, the light emitting area of the second light emitting surface 121 and the light emitting area of the third light emitting surface 131 are sequentially staggered. In order to avoid mutual overlapping between the multiple light emitting areas and interference with light emission, on the projection plane of the light rays, the light emitting area of the first light emitting surface 111, the light emitting area of the second light emitting surface 121 and the light emitting area of the third light emitting surface 131 are sequentially staggered. In this embodiment, the light emitting area of the first light emitting surface 111 is located at the part of the first light emitting surface 111 close to the outer edge, and the light emitting area of the first light emitting surface 111 only occupies a part of the first light emitting surface 111; the light emitting area of the second light emitting surface 121 is located near the outer edge of the second light emitting surface 121, and the light emitting area of the third light emitting surface 131 is located at a part of the third light emitting surface 131. By staggering the multiple light emitting areas, multiple beams of outgoing light rays do not interfere with each other and are uniformly distributed on the entire light emitting side, ensuring the light emission effect.

[0049] According to one embodiment of the present application, the light emitting areas of the first light emitting surface 111 and the second light emitting surface 121 are both distributed with a plurality of microstructures 140 connected to each other; the light emitting area of the third light emitting surface 131 is selectively provided with the microstructure 140, that is, the light emitting area of the third light emitting surface 131 can be provided with the microstructure 140 or not. Since the third light emitting surface 131 is located at the bottom surface of the lens body 100, after the lens body 100 is installed in the shell 300, the bottom surface of the shell 300 is provided with a light mixing plate, the third light emitting surface 131 is relatively close to the light mixing plate, and through the light mixing effect of the light mixing plate, the microstructure 140 can be omitted on the third light emitting surface 131, which can save the processing procedure and cost.Figure 2 As shown in the figure, the microstructure 140 of the second light exit surface 121, the microstructure 140 of the other light exit surface and the microstructure 140 of the second light exit surface 121 are consistent in shape, each microstructure 140 refracts a substantially same light spot and overlaps, achieving effective light mixing effect, thereby solving the problem of uneven light color of the light source itself, without etching or film processing of the lens, reducing the cost.

[0050] In the embodiment, the microstructure 140 is a convex curved surface or a hemispherical surface connected to each other, and of course, can be other structure forms, which are not limited in the embodiment.

[0051] In order to simplify the processing, the embodiment adopts the microstructure 140 only processed on the light exit area of each light exit surface, and of course, the microstructure 140 can be processed on the entire first light exit surface 111, the second light exit surface 121 and the pair of third light exit surfaces 131, which are not limited in the embodiment.

[0052] According to one embodiment of the present application, in order to optimize the structure, the second light entrance surface 123 is set as a convex first arc surface, in order to form the required incident angle, the third light entrance surface 134 is set as a convex second arc surface, and the third light exit surface 131 close to the side where the second light exit surface 121 is located is set as a convex third arc surface 1311, that is, the third light exit surface 131 adjacent to the second reflection plane 133 is set as a convex third arc surface 1311, the third arc surface 1311 is relatively flat, and the required arc can be set according to the requirement, by setting the third arc surface 1311, the emitted light rays passing through the third arc surface 1311 are converged, so that the light rays are offset below the third arc surface 1311, thereby avoiding the emitted light rays of the opposite third light exit surface 131, achieving better light emitting effect. The two third light exit surfaces 131 form a triangular gap.

[0053] On the other hand, as shown in the figures, Figure 1 , Figure 4 and Figure 5 The embodiment of the present application further provides a lighting lamp, which comprises:

[0054] A light source 200, which can be a LED light source;

[0055] The light source 200 is installed in the light source installation groove 150, and the light source 200 provides incident light for the first light entrance surface 113, the second light entrance surface 123 and the third light entrance surface 134, and deflects the light out of the first light exit surface 111, the second light exit surface 121 and the third light exit surface 131 by a certain angle, thereby achieving the effect of polarization. For some special installation occasions, for example, when the lower surface of the eaves cannot be installed with a lighting lamp due to the narrow space, the lighting lamp of the embodiment can be installed on the wall on one side of the eaves. Since polarization can be achieved, the same downward illumination effect can be achieved. In addition, the installation space of the wall is larger, and the installation is more convenient than the installation under the eaves. The polarization lens of the embodiment is in a strip shape, has a large light emitting area, and can be used as a wall washing lamp.

[0056] In order to facilitate the installation of the polarization lens, according to an embodiment of the present application, a shell 300 is further included, and the installation side of the lens body 100 is installed in the shell 300 and abuts against the first side wall 310 of the shell 300; the first side wall 310 is installed on one side of the wall of the shell 300, and the shell 300 also protects the light source 200 and the polarization lens.

[0057] In the embodiment, the top surface of the shell 300 is inclined downward from the first side wall 310 to the opposite second side wall 320. Therefore, the top surface of the shell 300 forms a shape similar to a triangle, occupies a small space, and is more suitable for installation in a narrow space under the eaves. The bottom surface of the shell 300 is the light exit side, and a bottom plate 330 made of transparent material is installed thereon, and the bottom plate 330 is provided with a light mixing structure to facilitate the realization of the light mixing effect and make the light color uniform and consistent.

[0058] In the embodiment, as shown in Figure 5 The number of light sources 200 is multiple, and the multiple light sources 200 are arranged in sequence along the extension direction of the light source installation groove 150, and the stretching length of the lens body 100 can be determined according to specific needs.

[0059] In summary, the polarization lens of the embodiment can position the power source 200 on the side close to the wall surface, rather than the lower surface of the eaves, and achieve the effect of deflecting the light out of the light exit surface by 90° on one side through the light control of the polarization lens itself, which is more suitable for special application scenarios.

[0060] It should be pointed out finally that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit the same; and although the present application has been described in detail with reference to the foregoing embodiments, it should be appreciated by those skilled in the art that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features thereof can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
